PIX to RB Converter

PIX is a raster image format originally developed by Alias Research (later Alias|Wavefront, then acquired by Autodesk) in the mid-1980s for use with their 3D animation and modeling software running on Silicon Graphics workstations. The format stores uncompressed 24-bit RGB image data in a straightforward scanline-by-scanline layout preceded by a minimal header containing the image width and height. PIX was the native output format of Alias's rendering engines, used to store individual frames of 3D animations and rendered stills from software that would eventually evolve into Maya, one of the most influential 3D content creation tools in entertainment history. The format's design reflected the priorities of high-end production rendering: raw speed for writing individual frames during batch renders, exact pixel fidelity with no compression artifacts, and compatibility with the hardware framebuffers used in professional compositing suites of the era. One advantage of PIX is its rendering pipeline heritage — the format can be read by tools throughout the VFX and animation industry, and legacy PIX sequences from Alias-era productions represent irreplaceable primary assets from foundational works in computer animation. The format's simplicity provides another practical benefit: with no compression overhead, metadata complexity, or container parsing required, PIX files can be read and written with minimal code, making them trivial to incorporate into custom rendering and compositing pipelines. PIX files are supported by ImageMagick, GIMP, XnView, and various professional compositing tools.
